How does the threshold stimulus influence muscle contraction?
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
Stimulus at which the muscle first contracts perceptibly?
Threshold stimulus
What result would be expected if an additional stimulus equal in intensity to the first were applied to the muscle at the 60 millisecond time point?
the muscle would increase in tension to a level greater than that measured at the beginning of phase C.
What has happened in the muscle when the maximal stimulus is achieved?
Each of the individual muscle fibers in the muscle are contracted when the maximal stimulus is achieved. Dr. H.
What is the definition of maximal stimulus?
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
What phase is between stimulus of a muscle and the shortening of the muscle?
belly
Which muscle characteristic describes the ability of muscle to respond to a stimulus?
Excitability
What the reaction to a stimulus by a muscle gland?
A Response
A muscle fiber will not respond to a stimulus until that stimulus reaches what?
it will not respond until it reaches the threshold level
What is the all none law of muscle response?
all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is not dependent on the strength of the stimulus. If the stimulus is any strength above threshold, the nerve or muscle fiber will give a complete response or otherwise no response at all
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
What is resting tension in a skeletal muscle called?
muscle tone
